WHAT IS CHOPPER TECHNOLOGY®? »» Multi-Process Welding, Separate Arc Gouge Mode Select one of five process modes, including CC-stick, downhill pipe (for stick), DC Touch Start TIG®, CV-wire or arc gouging mode which maximizes output with up to 1/2 in. (12.7 mm) carbon rods. »» Plenty of AC Generator Power 20 kW continuous 3-phase 240V AC generator power will operate industrial equipment such as plasma cutters, pumps, inverter welders and grinders. 12 kW continuous 1-phase AC generator power for common construction tools and lights. »» Stainless Steel Enclosure Standard stainless steel roof, side panels and engine-access door deliver added protection, durability and corrosion-resistance. Eliminates need to replace these items due to paint damage or rust. Traditional weld control is more variable around the desired output. Chopper Technology delivers extremely fast response for tighter output control. Patented and award-winning Lincoln Electric Chopper Technology delivers superior DC arc welding performance for general purpose stick, downhill pipe, DC TIG, MIG, cored-wire and arc gouging. Benefits of Chopper Technology include: - Easy arc starting - Smooth arc action - Low spatter levels - Excellent bead appearance •VRD® (Voltage Reduction Device™) reduced OCV (Open Circuit Voltage) in CC-stick, CV-wire and arc gouging welding modes for added safety. • Arc gouging mode maximizes output for up to 1/2 in. (12.7 mm) carbon rods. Easy starts, especially with VRD™ on. • CC-stick mode is optimized for general purpose stick using E7018 low hydrogen electrode. • Excellent CV wire welding with cored-wire and MIG (CO2 and mixed gas). WHAT IS VRD? The VRD® (Voltage Reduction Device) provides additional safety in the CC-stick, CV-wire and arc gouging weld modes, especially when working in an environment with a higher risk of electrical shock such as wet areas and hot, humid, sweaty conditions. The VRD reduces the OCV at the welding output terminals while not welding to less than 30 volts DC. The VRD is activated by flipping a toggle switch inside the machine to the “ON” position. Indicator lights monitor the voltage: green for less than 30 volts while not welding, and either red (greater than 30 volts) or green while welding, depending on the actual voltage of the arc. Other weld modes when VRD is on: Downhill Pipe – There is no output. Touch Start TIG – No difference in operation. TIG is normally a low voltage (less than 30 volts) operation. VRD portion of nameplate with green light on. • Built-in “hot” start in CC-stick and CV-wire modes for easier starts and restrikes minimizing the electrode “sticking” to the work. • Downhill pipe mode has arc force control for enhanced pipe welding. The pipe mode is excellent for cellulosic electrodes and facilitates fast travel speeds, especially on fill passes. Adjust the arc force for a soft, buttery arc or a more forceful digging arc. • Standard DC Touch Start TIG® welding, not scratch start, for easy arc starting that avoids tungsten contamination and the need for high-frequency. PERFORMANCE Air Compressor Performance • Compressor is belt-driven from the engine using a magnetic clutch. Includes an automatic belt tensioner for optimal compressor performance. A pressure sensor avoids excessive clutch wear by preventing clutch engagement when high compressor back pressure exists. • The compressor can be conveniently turned on or off with an easy-toreach toggle switch located on the control panel. The full output of 28.3 liters/second (60 SCFM) is available when the engine is set to high idle mode, or 18.9 liters/second (40 CFM) of output in low idle mode. • The air shut-off valve can easily be closed for connecting and disconnecting an air hose. The valve is located in a recessed area below the control panel for convenient access and protection against accidental impact. • The compressor automatically shuts down for high temperature. An indicator light on the control panel turns on for this condition. The compressor automatically becomes operational when the temperature returns to normal. • Compressor maintenance items such as filters are easily accessed in the single-side-service engine compartment. The drain connection for the valve and compressor oil is located in the base of the engine compartment. Recommended 500-hour maintenance intervals minimize system service frequency. • An optional field-installed air filter kit minimizes water content in the supply air. This avoids cold weather air hose ice up. The compact kit installs on the case side of the Air Vantage 800 or to a nearby service truck wall. • A minimum pressure air check valve is included to improve compressor shutdown when the compressor shut-off valve is occasionally left open. Generator Performance • Simultaneously weld and use 3-phase AC power – for example, up to 12,000 watts can be delivered while welding up to 400 amps. Compare to competitive product which has 3-phase power available as an extra-cost factory-only option. • 3-phase 240V receptacle on control panel eliminates the need to hard-wire the connections. Compare to competitive product which usually requires hard-wired connections. • The Air Vantage 800 provides added value at the job site by delivering up to 12,000 watts of 1-phase AC auxiliary power for equipment such as a Lincoln Electric plasma cutter. Also use for lights, grinders and other common construction tools. Compare this to the common competitive standard of 4,000 watts of single phase AC power. No expensive options are required to add significant generator capacity. • Simultaneously weld and use AC power – the full 12,000 watts (1 or 3-Phase) can be delivered while welding up to 400 amps. Plug in a Lincoln Electric Invertec® V275-S for a second arc. • Nominal 120V and 240V AC generator voltage is independent of any weld dial setting. • 120V receptacles are GFCI (Ground Fault Circuit Interrupter) protected with sealed GFCI units. • All receptacles are circuit breaker protected.
